The working principle is as follows: when the device is required to be used, the device is placed in a working area, then power supplies of all drives in the device are connected, the device is in a standby state, and the device can be normally used (refer to figure 1, and figure 1 is a top cross sectional view of the structure), when the device is used, a steel pipe firstly enters from the right side through a conveying belt, after one end of the steel pipe extends into a conical positioning cylinder 63, the conical positioning cylinder 63 plays a guiding role, so that the steel pipe can be smoothly sleeved on the conical positioning cylinder, and after a starting end of the steel pipe shields a second infrared receiver 64 along with the advance of the steel pipe, infrared rays emitted from a second infrared emitter 62 cannot be reflected, so that signals are transmitted to a PLC controller 3 at a control console 2, so that the PLC controller 3 retracts a plurality of electric telescopic rods 53 at the right side, and an insert block 57 is retracted through a T-shaped rod 56, the insertion block 57 is no longer clamped with the second movable rod 49 on the right side, so that under the pushing of the steel pipe, the second movable rods 49 start to displace, and thus the second movable rods 49 are tightened to the fixed column 42 on the right side like an umbrella (the first hinge block 47, the second hinge block 58 and the third hinge block 59 are arranged, so that the second movable rods 49 form a hinge structure, thus ensuring the normal completion of the work), so that the steel pipe can be inserted into the fixed column 42 on the right side along the steel pipe, then the steel pipe is slowly sleeved on the stabilizing column 13, when the steel pipe is superposed with one end of the stabilizing column 13, because the plurality of transmission belts 65 are arranged, the starting end of the steel pipe starts to contact with the transmission belts 65 on the right side, and the two sides of the transmission belts 65 are set to be arc shapes, thus avoiding the steel pipe from being clamped, and thus enabling the steel pipe to be smoothly sleeved on the stabilizing column 13, and because the plurality of transmission belts 65 are arranged obliquely, the steel pipe is driven to rotate while moving, and when moving, the steel pipe is prevented from being cheap due to the limit of the stabilizing column 13, and when the steel pipe rotates (refer to fig. 15, the dotted line in the figure indicates the steel pipe, fig. 15 is a sectional view of fig. 1, a hydraulic cylinder 68 is arranged, so that the hydraulic cylinder 68 drives the bearing plate 69 to rise, so that the plurality of transmission belts 65 are tightly attached to the bottom end of the steel pipe, and a friction layer is arranged on the outer surface of the belt of the transmission belts 65, so that the friction force can be increased, the steel pipe is driven to rotate, at this time, the hydraulic cylinder 68 is continuously raised, so that the top end of the steel pipe is contacted with the plurality of second polishing sheets 79, and the stopper 77 compresses the fifth spring 78, until the inner surface of the steel pipe is contacted with the first polishing sheet 21 at the bottom end, thus the rising is stopped, and the steel pipe is polished by the first polishing sheet 21 and the second polishing sheet 79, thus, the inner wall and the outer wall are simultaneously polished in the moving process, meanwhile, on one hand, connecting blocks 32 are arranged on two sides of the stabilizing column 13 (two ends of the stabilizing column 13 are respectively connected with a sliding rod 31, the sliding rod 31 is in sliding connection in a groove 38 through a second sliding block 40, a rubber ring 29 and a telescopic hose 30 are arranged to play a role of buffering, and the sliding rod 31 can be effectively prevented from being clamped by a foreign matter in a sliding way, the sliding rod 31 is a square rod, therefore, the sliding rod can only slide with the connecting blocks 32 and can not rotate, the connecting blocks 32 are fixed, therefore, the stabilizing column 13 is also fixed, the problem that the stabilizing column 13 is driven to rotate when the steel pipe is polished is avoided, a second cavity 37 is arranged in the connecting blocks 32, a storage battery 36 is arranged in the second cavity 37, and a first vibrator 41 is also fixedly arranged on one of the second sliding blocks 40, so that the stabilizing post 13 can transversely and rapidly move left and right, and rub against the inner wall of the steel pipe through back-and-forth movement, thereby ensuring that the steel pipe can perform grinding work, on the other hand, the arc cover 12 is provided with the sliding frame 75 in a laminating manner, the sliding frame 75 is fixedly connected with the sliding sleeves 71 through the two arc plates 73, the arc plate 73 is provided with the second vibrator 74, after starting, the sliding frame 75 can rapidly move back and forth, so that the second grinding pieces 79 can rapidly move in the movable groove 80, thereby rubbing against the outer wall of the steel pipe, thereby ensuring that the outer wall of the steel pipe can perform grinding work, so that the steel pipe can move while grinding (because the steel pipe moves while rotating under the transmission of the transmission belts 65), when the starting end of the steel pipe comes to a place flush with the first infrared receiver 33, at this time, the second infrared emitter 62 can normally perform a reflection operation with the second infrared receiver 64, so that the plurality of second movable rods 49 on the right side are reset (the third spring 45 is disposed in the second chute 44, so that the first movable rod 48 is displaced to push the second movable rod 49 to reset, and the electric telescopic rod 53 is also started to extend after one second of the reflection operation of the second infrared emitter 62 and the second infrared receiver 64, so that the second movable rod is opened and closed again, and a delay time of 1 second is set, so that the abnormal resetting caused by the slow resetting of the second movable rod 49 is avoided), so that the right side is reconnected, and the left side starts the umbrella-shaped contraction operation, so that the steel pipe can be accurately discharged, and when the starting end of the steel pipe reaches the guide column 43, the driving roller 6 is disposed, the driving roller 6 is driven by the first driving motor 5, and a plurality of spring cylinders 8 are arranged below the U-shaped frame 4, so that the bottommost end of the steel pipe can be attached to the top end of the driving roller 6, and the top end of the driving roller 6 is in the same horizontal plane with the top end of the transmission belt 65, so that the steel pipe can be assisted to move under the driving of the driving roller 6, the steel pipe is discharged and smoothly arrives at the left conveying belt for conveying, and after the steel pipe is completely discharged, the second movable rod 49 at the left side is reset, so that the next steel pipe can be polished (when two adjacent steel pipes are polished, the polishing time of one steel pipe is staggered, the second movable rods 49 at two sides are prevented from being opened simultaneously, so that the stabilizing column 13 is separated from the arc-shaped cover 12), thereby realizing the continuous polishing of the steel pipe, being simple and convenient to operate, and simultaneously polishing the inner and outer walls of the steel pipe, greatly improving the working efficiency and saving the cost investment of enterprises.

And a first cavity 14 is arranged in the stabilizing column 13, when the inner wall of the steel pipe does not need to be polished, the second driving motor 15 is started, the first threaded rod 16 and the second threaded rod 18 rotate, the two threaded sleeves 17 move towards two sides, the first polishing pieces 21 retract into the through groove 20, the inner wall of the steel pipe can not be polished, equivalently, when the batches of the steel pipe are different, the thickness and the diameter of the steel pipe are different, the extending length of the first polishing pieces 21 can be adjusted by starting the second driving motor 15, the device can be guaranteed to be capable of polishing different steel pipes, the practicability of the device is guaranteed, and the device has a widely used function, an arc-shaped scraping piece 81 is arranged at one side of the first polishing piece 21 at the lowest part (the model of the arc-shaped scraping piece 81 is adjusted according to the batches of the steel pipe), and the arc-shaped scraping piece 81 is adjusted through the plugboards 82, Articulated piece 83 of fourth, the preforming 84, joint spare such as fixture block 85 and sixth spring 86 carries out the joint with slot 87 and draw-in groove 88 that first abrasive disc 21 one side of below set up, can make the piece of steel pipe inner wall department carry out simple cleaing away like this (arc doctor-bar 81 adopts rubber materials to make, can not harm the inner wall of steel pipe, and the material is softer in first abrasive disc 21, consequently can wear and tear along with first abrasive disc 21, avoid producing the phenomenon that the card is pause), and easy operation is convenient, it is all relatively easy to dismantle the installation, can not influence work efficiency.
